The package doctools::msgcat::idx::en is a
support module providing the EN (english) language message catalog
for the docidx parser in the doctools system version 2. As such it is
an internal package a regular user (developer) should not be in direct
contact with.

Within the system architecture this package resides under the package
doctools::msgcat providing the general message catalog
management within the system. Note that there is no
explicit dependency between the manager and catalog packages. The
catalog is a plugin which is selected and loaded dynamically.

This document, and the package it describes, will undoubtedly contain
bugs and other problems.
Please report such in the category doctools of the
Tcllib Trackers.
Please also report any ideas for enhancements you may have for either
package and/or documentation.
